02 Nov 1983TL;DR: In this article, an arrangement for the protection of a transistor, particularly a MOSswitching transistor including a zener diode connected between the gate and source terminals for limiting the gate potential and a switch-off transistor connected to the control circuit of the MOS-transistor for grounding the gate thereof and switching it off is presented.
Abstract: An arrangement for the protection of a transistor, particularly a MOS-switching transistor including a zener diode connected between the gate and source terminals for limiting the gate potential and a switch-off transistor connected to the control circuit of the MOS-transistor for grounding the gate thereof and switching it off. First and second monitoring circuits are coupled between the MOS-transistor and the switch-off transistor for producing a signal switching on the switch-off transistor in response to a drop in the load current and an increase in the output voltage of the MOS-transistor. First and second timing circuits block the signals of the monitoring circuits for predetermined intervals.

Abstract: A parallel connected gate turn-off thyristor device including an additional short circuiting conductor connected between the gate terminals of the respective gate turn-off thyristors so as to bypass a part of the turn-on and turn-off gate currents of one gate turn-off thyristor to other gate turn-off thyristors to increase the turn-on and turn-off gate currents of the other gate turn-off thyristors thereby hastening the turn-on and turn-off operations of the other gate turn-off thyristors.

TL;DR: In this article, a ramp-operated mechanical gate system, including vertically swinging gate, sliding gate, and side-swinging gate, is described, which utilizes collapsible ramps to supply energy to open a gate so that the gate is opened automatically when the collapsible ramp is depressed by an approaching vehicle and is closed automatically when vehicle drives through the gate and the ramp is no longer depressed.
